Convenient short plug to power up refrigerator or work on projects while parked at home. Good to have in case the 50A plug malfunctions.
It will help me keep my RV charged with a simpler system rather pulling out the heavier and bulky 50 amp cord.
Product worked great and Etrailer had it in stock!
Diane's follow up was excellent! I definitely recommend etrailer.
Excellent quality and it reduces dependance on the 50A cord for routine low power needs. retrained has an aewesome inventory of parts and accessories for all trailering needs. Great customer service and follow-up on my order.
Switched out 2020 Airstream Classic to the SmartPlug system, and needed a way to provide power to charge the batteries and operate the lights and fans, while in storage. The 50 to 15 AMP adapter is well made, with all connections being cast, eliminating any possibility of weather intrusion.
As ususal Teri N is awesome to deal with, trailer is hard to be for customers service.
Great service, you are the go too for towing and camper equipment. Thank for all the great service your staff provides.Ed P.
I realize this is a user specific device but to anyone who has converted their rv to the 50amp smart plug this is very expensive but also very worth it I no linger will need my 50’ 50 amp cord coiled up under the trailer when it is plugged into the 15amp circuit to our house Excellent quality and extremely handy
Quite expensive for a pigtail, but works great!
Worked perfectly for our camper! No complaints highly recommend
Extremely well built! You get what you pay for, even though it's quite expensive.
Once in stock received the product quickly and it did exactly what I wanted it to do.

Have had this for a year and use it all the time, great to apply power using a standard extension cord when I don’t need 30 or 50 amp service,.
Perfect OEM fit for my Airstream Trailer. This will provide the seamless power needed to keep my batteries topped up!
Works great! Fits tight, nice having the light that shows it’s plugged in. Very pleased with the plug.
Built well but shipping took 13 days.....that's a little too long. Next time I will pay the extra money. Still...yal are a SUPER company!!!!

Its been a year since my initial review. Adapter has been used dozens of times, and it has performed flawlessly. It has proved its reliability. No worries about buying this item.
Just what is needed to hookup trailer to house current for precamping setup

I am glad to hear this is working well for you! What kind of trailer are you using this with?
This adapter is exactly the right solution to keep the Lithium batteries on my Classic Airstream charged. My storage facility provides a 120V connection for this purpose, and I have the right dog bone adapters to use the AS factory shore cable. But I'd rather not have the expensive factory cable lying about for security reasons. I put a 30' 10 gauge 15 amp extension cable on this that cost about $40.
Moochdocking Solution for your late model Airstream
Moochdocking or just keeping the batteries and fridge going? This is the neat convenient solution. Indicator light on the plug let you know your power is good.
I use it at the house and at my indoor storage.
Highly recommended

Love the sales pitch, Paul! Glad it's been a good choice for the Airstream over the months. Are you a full-timer with your Airstream?
